    Can anyone help? I need a 5 Kilohertz power supply, 10 VAC, 2 amps, regulated.

    Thank you,
    Bill

    Audio amplifier? With sine wave generator on the input.

    This is needed for testing autopilot gyros for aircraft.

    1. What is the shape of the AC wave?
    2. 10 Volts peak to peak, or just peak?
    3. If it is a square wave, what is the rise and fall time required?
    4. If it is a sine wave, how accurate does the waveshape need to be?

    Ideally a sine wave with 10 volts RMS regulated with very little noise. The input could be 12 VDC or 115 vac 60 Hz.

    Thank you very much for any help,
    Bill

    10V RMS = 28.28V You will need a 30 to 35V DC power supply. You could use a power transformer, but at the frequency you have selected it won't be that practical. Basically you are wanting to make a simple inverter. IMO you will need a precision sine wave with a stable amplitude, a PWM modulator, and a full H bridge circuit. Did my description make sense to you (checking your electronics background)?

    I also have 28 VDC available as a source. Could this work?

    Don't aeronautics instruments have to be certified? How are you(O/P) going to get this certified? The forum does not allow automotive modification threads so I doubt that this thread will survive long. Who wants a plane to drop from the sky?

    Some things are better off being bought and this would be one of them.
